California cows to supply renewable gas energy
San Francisco Chronicle, March 4, 2008

"Pacific Gas and Electric Co. will unveil its latest renewable energy
project today, a system that collects methane from manure on a Fresno
County dairy farm and refines it into biogas, virtually identical to
natural gas. The biogas then flows into a PG&E natural gas pipeline for
use in homes and power plants.

The San Francisco utility gets a new source of fuel. The farm gets a new
source of income. And the methane, a potent greenhouse gas, stays out of
the atmosphere.

PG&E estimates that biogas could one day supply 5 percent of all the
natural gas the utility needs."
